Detailed Description
Dental implants have become a standard treatment in the replacement of missing teeth. After tooth extraction and implant placement, resorption of buccal bundle bone can pose a significant complication with often very negative cosmetic impacts. Remodeling of the labial bone plate after extraction is a common challenge that affects the final esthetic outcome especially in the esthetic zone.
In addition to, marked bone loss in the horizontal plane and vertical height of the socket wall occurs during the first year after extraction, and one third of this total bone loss occurs during the first three months.
As the buccal aspect of the dental implant has great importance, especially in the aesthetic zone, because the buccal bone is very thin especially in the anterior maxilla and its resorption can result in recession of the soft tissue.
It was suggested that following tooth extraction, the blood vessels in periodontium to the thin bone walls are severed, thereby causing facial bone plate resorption. Thus, it can be assumed that retaining a root may alter the occurrence of facial bone resorption. Many studies showed that the retention of the decoronated root, vital or endodontically treated as root submerge technique, can preserve the alveolar bone.
Other studies also proved that the placement of the implant in contact with retained root surface preserved the buccal bone and led to good emergence profile, Hürzeler et al. (2010) were the first to demonstrate the socket-shield technique in a study on one beagle dog. Were Modification of original technique was done by many researchers by preserving the palatal bone and proximal bone. The promising result of this study shows socket shield technique as a feasible alternative treatment option for thin buccal plate region area and periodontally healthy teeth.
Flapless technique can decrease the amount of bone resorption. Thus, helping in preservation of the inter-dental papilla. Also, it provides less traumatic surgery, decreased operative time, rapid healing and less postoperative complications.
The socket-shield (SS) technique provides a promising treatment adjunct to better manage these risks and preserve the post-extraction tissues in aesthetically challenging cases. The principle is to prepare the root of a tooth indicated for extraction in such a manner that the buccal / facial root section remains in-situ with its physiologic relation to the buccal plate intact.
The socket shield procedure is a novel technique for post extraction implant placement. Several modifications of partial extraction therapy and simultaneous implant placement have been presented since its inception. In this study we discuss the most contemporary step-by-step surgical technique of the socket shield procedure with detailed illustrations and representative cases.

Outcome Measures
Primary Outcome Measures
- change of labial bone thickness [baseline at day of surgery and after 6 months]
With the help of CBCT ;Horizontal bone level measurement: Three horizontal lines are drawn 2, 4, and 6 mm apical to implant platform to outer surface of buccal plate of bone. Facial plate of bone is taken as a reference point and is measured baseline (after implant placement and at 6 months follow up).
Secondary Outcome Measures
- Pink esthetic score (PES) [baseline presurgery and after 6 months]
Pink esthetic evaluation criteria: The Pink Esthetic Score is based on seven variables: mesial papilla, distal papilla, soft-tissue level, soft tissue contour, alveolar process deficiency, soft-tissue color and texture. Each variable was assessed with a 2-1-0 score, with 2 being the best and 0 being the poorest score. The mesial and distal papilla were evaluated for completeness, incompleteness or absence. All other variables were assessed by comparison with a reference tooth, i.e., the corresponding tooth (anterior region) or a neighboring tooth (pre-molar region) or evaluate (PES) evaluation before extraction and at six months follow up of involved tooth.
